About PlotPilot
What this is
PlotPilot is a free, offline-first garden planner. It helps you sketch your plot, plan plantings around your frost dates, track seed inventory and germination tests, learn about beneficial insects, and preview your garden in 3D. All your data stays in this browser (localStorage) — there is no account and no backend.
Disclaimers
- Frost dates, hardiness zones, and sun estimates shown in this app are approximations. Always verify with your local cooperative extension service before making planting decisions.
- PlotPilot is a heuristic planning tool, not professional advice. It does not replace guidance from horticulturists, extension agents, or pest-management professionals.
- Location lookup uses the public OpenStreetMap Nominatim service; coordinates are approximate. You can always enter latitude/longitude manually.
